Fogging the Engine
Fogging the engine with Polaris fogging oil or a similar commercial alternative is one of the most important storage steps a rider can do to make sure the internal parts of the engine do not rust and corrode during the storage season.
To fog the engine, do the following:
-
Remove the spark plugs from the engine.
-
Liberally spray fogging oil into each spark plug hole. If possible, have an assistant slowly pull on the recoil rope to rotate the engine while spraying the oil into each cylinder.
-
Loosely install the spark plugs.
NOTICEDo not install new spark plugs after fogging the cylinders. Fogging oil prevents the formation of rust/corrosion by sticking to the internal engine components – including the spark plug electrodes. Replace these spark plugs the following season after all of the fogging oil has been burned out of the engine.
